Flying Dutchman Shuttle designed by Jan Louët has some very useful design features. First, the metal wire bowed across the top of the shuttle, spreads apart sticky warp threads. Second, the plastic guide in the front allows for optimal unwinding of your bobbin. Shuttles are lacquered 13.5 "x 2.75" x 2", weight: 5.7 oz made of lacquered beech. Use with paper quills or 5" Schacht bobbins.
